The zone of inhibitions produced ranges between 16 mm and 17 mm for the bacterial strains while zone of inhibitions of 30 mm and 35 mm was produced by the fungal strains. The MIC produced, ranges between 0. The results of mineral element analysis showed the presence of the following elements at various concentrations: This present research has validate the ethnomedical uses of the plant in the treatment of skin parinari macrophylla.

The seeds were cleaned, de-shelled and well dried and ground using laboratory plastic pestle and Mortar prior to extraction.

Oil Yield The oil which parinari macrophylla recovered by complete distilling of most of the solvent on a heating mantle was then transferred to measuring cylinder. A yellow precipitate was formed which indicated the presence of tannins.

Test for saponins The oil extract was diluted with 2 ml of parinari macrophylla water and it was agitated in a test tube for about 15 minutes.

The formation of 0.

Test for flavonoids Few drops of dilute sodium hydroxide were added to 1ml of the oil extract in a test tube. An intense yellow color was formed which turned colorless on addition of few drops of dilute acid indicating the presence of flavonoids. Test for alkaloids The oil extract 2ml was added to 2ml of HCl.

An orange or red precipitate was immediately formed which indicated the presence of alkaloids. Test for steroids To 1ml of the oil extract in a test tube, 10 ml of chloroform was added.

Equal volume of concentrated sulphuric acid was added by the sides of the test tube. The upper layer turned red, whereas the sulphuric acid layer turned yellow with green fluorescence. This indicated the presence of steroids. Test for terpenoids Two ml of the oil extract was mixed in 2 parinari macrophylla of chloroform, and concentrated H2SO4 1 ml was carefully added to form a layer.


A reddish brown coloration was formed at the interface to show positive results for the presence of terpenoids. Test for cyanogenic glycosides Small quantity of the oil extract was put in a test tube. The test tube was stoppered with a cork containing a strip of picrate-impregnated paper hanging down from the stopper, and parinari macrophylla at ambient temperature for 2 hours.

West African Plants

A color change of the paper, from yellow to brown-red, indicated the release of HCN by the plant. If there was no release of HCN within 2 hours, indicating a negative test, the tube was left at ambient temperature for 24 and 48 hours, so that it could be re-examined.

A brown-red parinari macrophylla within 2 h indicated parinari macrophylla presence of cyanogenic glycoside and the respective hydrolytic enzyme, and the plants were considered cyanogenic in the field.

A brown-red color appearing within 48 hours indicated that the cyanogenic glycoside spontaneously released HCN without the action of enzyme.


No color change after 48 hours indicated that the test was negative for cyanogenic glycoside. Parinari macrophylla analysis The acid value, iodine value and saponification value determinations were carried out using the methods reported [ 101112 ].

Parinari macrophylla Sabine

Free fatty acid was determined according to the Official Method Ca 5a [ parinari macrophylla ] while peroxide value was determined using the method specified by International standard organization [ 14 ].

Observations and Results Discussion The results of qualitative phytochemical analysis on the oil extract of Parinari macrophylla seed oil are shown in Table1.
